Hello. If VLC player caused any damage to the speakers it would be permanent physical damage, so changing your sound card would not help with that. Anyway the sound card is on the mother board and can't be changed.
If you have Dell Diagnostics audio tests on your laptop [note that not all models have it anymore] then run it. If you hear audio from your speakers and it sounds normal then the speakers are okay. If you can run Dell Diagnostics audio tests and you do not hear any audio through the speakers during the tests, then some part of your audio hardware has suffered a failure. It could be the speakers or a loose connection.
If you cannot run Dell diagnostics audio tests then another test that is just as good is to restore the laptop to the original factory configuration. That will fix the problem except in cases where the hardware has failed, so you will either have a solution or at least you will know that you need a repair.
If you decide to contact Tech support, I suggest that you remove VLC before they have a chance to find it on your system.
